The Grootrivierhoogte Pass forms part of the exceptionally beautiful route through the Southern Cederberg, connecting farms like Kromrivier, Matjiesrivier, Nuwerus and Mount Ceder, with the plateau of the Koue Bokkeveld. The road is made up of two major passes - the other being the Blinkberg Pass. Both offer stunning mountain scenery in crisp mountain air. The passes are seriously steep in some places - as steep as 1:5 !!!

The Grootrivierhoogte Pass is one of the steepest along this route and light front wheel cars will struggle on the final section near the summit in wet conditions, but for the vast majority of the year, this pass is doable in any vehicle. Take time to stop at the summit and allow the mesmerising mountain views to captivate your soul. From the summit one can look to the south and see part of the Blinkberg Pass, whilst the northern view includes Nuwerus, and Cederberg Oasis.

Like its neighbouring pass, Katbakkies Pass, the Peerboomskloof Pass was originally carved out by the local Khoi people as a cattle path. Farmers later used it as a wagon road to cross over the mountains from the Koue Bokkeveld to the Ceres Karoo. Only recently tarred and 4,5 km long, it provides picture-perfect views of the open, rugged expanse of the Tankwa Karoo and the mountain range separating it from the Koue Bokkeveld.

The first 2 km of the pass are tarred and sports a stiff gradient of 1:7. This tarring was done fairly recently and the road remains narrow with no road markings, so don't be fooled by the tar surface as it is still a dangerous pass. The pass initially enters the bottom end of the poort via an S-bend. The second part of the bend is very sharp and immediately a gravel track leads off to the left which goes to a picnic area. Once the top of the tarred section is reached at 704m ASL, the surface is once again gravel, but the gradient initially remains steep as the road heads up towards the plateau section, whereafter the gradients ease off to a more comfortable 1:20. The upper portion of the pass is relatively easy.
